Class IIOByteBuffer

A class representing a mutable reference to an array of bytes and
an offset and length within that array. IIOByteBuffer
is used by ImageInputStream to supply a sequence of bytes
to the caller, possibly with fewer copies than using the conventional
read methods that take a user-supplied byte array.

The byte array referenced by an IIOByteBuffer will
generally be part of an internal data structure belonging to an
ImageReader implementation; its contents should be
considered read-only and must not be modified.
